Quantum walk as a simulator of nonlinear dynamics: Nonlinear Dirac equation and solitons
Chang-Woo Lee, Paweł Kurzyński, Hyunchul Nha
Quantum walk (QW) provides a versatile tool to study fundamental physics and also to make a variety of practical applications. We here start with the recent idea of {\it nonlinear}…
Quantum macroscopicity measure for arbitrary spin systems and its application to quantum phase transitions
Chae-Yeun Park, Minsu Kang, Chang-Woo Lee +3
We explore a previously unknown connection between two important problems in physics, i.e., quantum macroscopicity and the quantum phase transition. We devise a general and computa…
Quantum phase estimation using path-symmetric entangled states
Su-Yong Lee, Chang-Woo Lee, Jaehak Lee +1
We study the sensitivity of phase estimation using a generic class of path-symmetric entangled states , where an arbitrary state …
Quantum plasmonic excitation in graphene and robust-to-loss propagation
George W. Hanson, S. A. Hassani Gangaraj, Changhyoup Lee +2
We investigate the excitation of quantum plasmonic states of light in graphene using end-fire and prism coupling. In order to model the excitation process quantum mechanically we q…
